CdFFEE-PERGOLATOR.

Specification of Letters Patent.

Patented June 15, 1915.

Application filed March 30, 1914. Serial No. 828,284.

T all whom it may concern:

Be it known that we, LOUIS BARABAS and JOSEPH I-IADA, subjects of theKing of Hungary, residing at Cleveland, in the county of Cuyahoga andState of Ohio, have invented certain new and useful Improvements inCoffee-Percolators, of which the following is a specification.

This invention relates to certain new and useful improvements in cofieepercolators.

The primary object of this device is to provide a return to the boilerfor the over flow of coffee caused from an overboiling of the same inthe percolator.

Another object is to provide a surrounding chamber for a coffee boileradapted to receive the overboiling coffee therefrom and to return thesame to the boiler through the outlet spout.

A still further object is to provide a coffee boiler with a foraminouscoffee-containing removable percolator and having the top thereofsurrounded by a chamber adapted to receive the overboiling coffee andreturn the same by means of a by-pass and the outlet spout to the boilerwhile the percolator is removable through a top opening of the chamher.

With these general objects in view and others that will appear as thenature of the invention is better understood, the same consists in thenovel combination and arrangement of parts hereinafter fully described,illustrated in the accompanying drawings, and pointed out in theappended claim.

In the drawings forming a part of this application and in which likedesignating characters refer to corresponding parts throughout theseveral views Figure 1 is a vertical central sectional view of thedevice, and, Fig. 2 is a horizontal transverse section taken upon line22 of Fig. 1.

Referring more in detail to the drawings, the coffee boiler 10 isillustrated as provided with an outlet spout 11 substantially of theusual form while an overflow chamber 12 is mounted upon and surroundingthe upper portion of the boiler and connected with sa1d spout by meansof the inclined by-pass 13.

The overflow chamber 12 is of dome shape and is provided with an annularrecess at its lower end that surrounds the upper end of the boiler andreceives the liquid in the boiler, and steam condensation when theliquid boils over, to return the same to the boiler by way of theby-pass 13.

A handle 14 is secured exteriorly between the casing and the boilerwhile a closure lid 15 is provided for the top opening 16 of thechamber.

A container or percolator 17 having a perforated bottom 18 and sides 19is suspended in the top of the boiler 10 by means of opposite springclips 20 while a perforated cover 21 is hinged upon the percolator andretained closed by means of the spring catch 22. The said catch 22 is ofsufficient strength to allow the percolator to be removed from its seatupon the top of the boiler by means of the ring 23.

The complete operation of the device will be at once apparent from theabove detailed description in that, the coffee being deposited in thepercolator is suspended Within the boiler while the necessary water maybe supplied through the opening 16 of the chamber 12 by opening the lid15 thereof. Upon an excessive boiling of the water and coffee, the sameboils over the top edge of the boiler 10 and into the chamber 12 andfrom the lower annular chamber portion 24 thereof it passes through theby-pass 18 and returns to the boiler by way of the lower portion of thespout 11. By opening the lid 15, the percolator is removed, by graspingthe ring 23 of the lid thereof and elevating Ehe same out of the devicethrough the cham- It will be noted by reference to Fig. 1, that the endsof the by-pass 13 are unobstructed, the object of this arrangement beingin a certain and positive manner to prevent any clogging of the by-passfrom coffee grounds that may escape from the percolator. This is afeature of importance, inasmuch as the location of the by-pass relativeto the spout and to overflow chamber is such that should a strainer becombined with the by-pass, such as is commonly the practice, it would bean exceedingly difficult matter to free it from any grounds and at alltimes to keep it in operative and sanitary condition. It will further beseen that the point of juncture of the bypass with the chamber 12 is atthe extreme lower end of the latter, thus to insure return of all of anycoffee that may escape from the percolator or body 10 into the chamber.

While the forms of the invention herein shown and described are what arebelieved to be preferable embodiments thereof, it is nevertheless to beunderstood that various forms and modifications may be had withoutdeparting from the spirit and scope of the invention as claimed.

What we claim as new is The combination with a cofiee pot and its spout,of an overflow chamber secured to the pot, and a by-pass communicatingwith the extreme lower endof the chamber and with Coplesot this patentmay be obtained for five cents each, by addressing the Commissioner ofPatents,

the spout, the two ends of the by-pass being unobstructed whereby toinsure return to the pot of any cofiee escaping to the chamber, withoutdanger of clogging.

In testimony whereof we aflix our signatures in presence of twowitnesses.
